Peoms of Cao Cao

Song of the Dew

Twenty kings have reigned in the House of Han,
But the former king employs a wavering man.
Like a monkey dressed in man’s attire,
He is ignorant but tricky, a perfect liar.
As he hesitates to put rebellion down,
The king is then abducted out of town.
When the rainbow lies across the sun,
The evil omen means that his life is done.
Dong Zhou usurps the power in great haste;
He kills the king and lays the capital to waste.
The House of Han is in peril during the clashes;
The ancestral temple soon is burnt to ashes.
The king has to move throne to the west,
The people sob on the way, deeply distressed.
When I look at the former capital town,
I feel a pang of sorrow for the crown.

Song of the Burial

Heroes in the east rise in revolt,
Attacking traitors like a thunderbolt.
When they raise troops to put rebellions down,
They plan to meet again in the capital town.
As the troops cannot be of one mind,
They hesitate and therefore fall behind.
They begin to fight against each other,
And even plot against their own brother.
The younger brother ascends the throne,
While the elder keeps a seal of his own.
Meanwhile, the soldiers are beset by lice,
And the people suffer worthless sacrifice.
Dead bodies scatter in the open air;
Not even cockcrow is heard anywhere.
The high death rate is beyond belief;
At thought of this, I’m benumbed with grief.

The lines of the seafood one seem to be out of order. The last 3 lines you have there belong right after "with this idea rooted in the mind".

The shrimps and eels which linger in the mud,Do not know how the seas and river flood.How can sparrows which hop about the hedge,Understand the flight of swans in full fledge?With this idea rooted deep in mind,You’ll tower over others of your kind.If you ride to the top of the Five Mounts,You’ll find that other mountains do not count.Those profit-seekers, on the other hand,Covet the wealth and power of the land.To serve the kingdom is my lofty yearning;To quell the country is my heartfelt burning.When I touch my sword, it roars like thunder;When I wave my sword, it flashes with wonder.For those who crave beyond what wishes ban,How can they understand the upright man?

I find the relative immediacy of this poem by Cao Cao to be incredibly fascinating; although he did not necessarily witness the exodus to the west from Luoyang, he lived and acted in events surrounding the incidents he mentions in the poem. Reminds me of a less-subtle Du Fu.
